Title: Semiconductor device
Inventor: KATADA MITSUTAKA
IPC: H01L29/68
Filed: 1989-01-31
Abstract: PURPOSE:To prevent a latch-up phenomenon from occurring in a semiconductor device of this design by a method wherein a current extracting layer, whose conductivity type is the same as those of well regions and which is to be connected to a source electrode, is provided between the well regions under a gate electrode. CONSTITUTION:A first conductivity type semiconductor layer is formed by diffusion in a part of a second conductivity type semiconductor layer 12 sandwiched between two or more well regions 131 and 132 under a gate oxide film 15 and connected to a source electrode 19 for the formation of a current extracting layer 24 which shunts a current introduced into the well regions 131 and 132 from the second conductivity type semiconductor layer 12. A part of a hole current introduced from the second conductivity type semiconductor layer 12 into two or more well regions 131 and 132 branches off to flow into the current extraction layer 24 and flows directly to the source electrode 19. As the current extraction layer 24 is located just under the gate, the layer 24 reduces a hole current which flows from the part just under the gate circuiting the part just under the source regions 141 and 142 and restrains the potential of the well regions 131 and 132 from increasing. By this setup, a semiconductor device of this design can be protected from a latch-up phenomenon.

IPC: H03K3/64
Filed: 1992-01-10
Abstract: PURPOSE:To prevent the circuit scale from being increased even when a variable bit range of phase difference data is wider by adding the phase difference data to a count of a counter. CONSTITUTION:A count outputted from a counter 1 to a signal path 2 is inputted to an adder 3.

Title: Push-button type tuner
Inventor: OOHASHI TAMAKI
IPC: H03J5/32
Filed: 1984-02-10
Abstract: PURPOSE:To reduce the width of a push-button tuner by providing just a forward operating function to a channel selection part which is actuated by a pressing operation only after excluding a preset function from an operation member and therefore a primary gear needed for a preset operation in order to reduce the array space between adjacent channel selection members. CONSTITUTION:A push-button 3 is pressed when it is set oppositely to a contact bar 22' of a stopper bar 15' provided to a channel selection member 12'. Then the member 12' set at the right side moves together with an operation member 1 owing to contact between a projected part 7b at one side and the bar 22'. While a lever 8 is switched every front-back movement of the member 1 and therefore channel selection members 12 and 12' set in parallel to each other can move alternately in the forward direction to work together. In addition, a channel selection piece 20 or 20' move back and forth with revolution of a manual shaft. As a result, a slide bar 42 is also moved back and forth. Then a variable tuning part 40 is controlled variably. Thus a presetting operation is attained. Furthermore the space between both members 12 and 12' can be reduced by at least the difference between the diameter of a primary gear of conventional constitution which is provided to the member 1 and the diameter of a shaft lever constituting the member 1.

Title: Analytical meter
Inventor: UCHIDA OSAMU
IPC: G01N1/26
Filed: 1978-03-01
Abstract: PURPOSE: To increase the response of analytical meter by shortening the time for mixing and substitution with the sample in the piping, by providing a bypass valve which cooperates with the flow path changeover in the prestage of a sample metering valve.  
     CONSTITUTION: Whan a flow path changeover valve 6B or 6D is open and sample B or D is passed into a sample metering valve 11 to be metered, a next analytical sample C or A is passed into a bypass valve 15 because the flow path changeover value 6C or 6A is opened and runs through a needle valve 9 and a flow meter 10 to be bypassed. Since this bypass flow rate is not limited, a large flow of sample may be passed. Besides, since the valves 6A and 6B have only a small contact with the sample flowing in other paths, the substitution may be achieved in a short time. When the sample B is completely metered and injected into a column 12, the valve 15 is changed over as shown by the dotted line, so that the sample C or A having been bypassed by the valve 15 will flow into the valve 11. Since the sample lead- in pipe 16 is short in length and small in inside diameter, the sample substitution time may be shortened.

Abstract: PURPOSE:To lighten a weight of an excavator, to reduce a volume thereof, and to enable steady supporting of a cutter boom base end, by a method wherein shoes, brought into press contact with guide channels, are mounted to both sides of an excavator. CONSTITUTION:Guide columns 4 are formed in the ground 30. Shoes 8 and 9 at both sides of an excavator are then fitted in guide channels 5 in the guide columns 4, and are brought into press contact with the guide channels 5 through expansion of an expander 2. Then, with an excavating cutter 10 turned, jacks 25 and 26 are alternately expanded and contracted to rock a cutter boom 11 to excavate a ditch hole 34. The expander 2 is then released, and is lowered under its own weight as the guide channel 5 guides a frame 3. The expander 2 is expanded again to excavate the ditch hole as described above. A cutter 22 forms the guide channel 5. Excavated dust are discharged through a suction discharge pipe 13 togetherwith mud water. After the excavating is complete, the excavator is lifted up.
